Nasal cirrus bearing forked tips. First dorsal fin higher or same height as second dorsal fin. Female body coloration white with 4-5 brownish-red H-bars; males black with 2 white bars below junction of 2nd and 3rd dorsal fin with caudal peduncle.

Adults inhabit rocky shores. They feed on algae (Ref. 9137). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
